Early restoration of the masticatory function, phonatory and aesthetics is some of the current goals of the therapy based on endosseous implants. Facing the classic protocols of implant insertion, which recommend a period of several months between extraction and implant placement, alternatives have been developed that demonstrate that immediate implant placement after tooth extraction permits a...

This study was conducted to determine the accuracy of bracket placement with the direct bonded technique. Ten orthodontic faculty members bonded a preadjusted orthodontic appliance on models of five cases of malocclusion in a simulated clinical situation (mannequin). A total of 50 sets of models served as the population of the study. Photographs of the models were measured to determine vertical...

Alveolar bone regeneration by means of titanium meshes is a widespread procedure, however to date, only few relevant studies were reported in literature concerning this technique. Consequently, the aim of the present systematic review was to analyze the reliability of the titanium mesh as a barrier, in conjunction with horizontal and vertical ridge reconstruction for implant placement purposes....

The impact of different assumptions concerning the source magnitude as well as the vertical placement of lightning-produced nitrogen oxides is studied using the global chemistry transport model MATCH-MPIC. The responses of NO x , O 3 , OH, HNO 3 and peroxyacetyl-nitrate (PAN) are investigated. A marked sensitivity to both parameters 5 was found. NO x burdens globally can be enhanced up to 100% ...

PURPOSE Tension band wiring is commonly used for fixation of simple transverse fractures. The popular configuration is parallel Kirschner wires (K-wires) and a stainless steel wire loop placed in a vertically oriented figure-of-8. METHODS We used a wooden model of a patella with a midway transverse fracture and compared four different types of fixation. The first construct had a vertical figu...

BACKGROUND This review addressed the focused question of what is the predictability of vertical ridge augmentation techniques for patients, who were diagnosed with insufficient alveolar bone volume for the placement of dental implants. MATERIAL AND METHODS A systematic online review of three main databases was performed between 1966 and 1 November 2007. Four groups of vertical bone augmentati...

BACKGROUND Public health research on sedentary behavior (SB) in youth has heavily relied on accelerometers. However, it has been limited by the lack of consensus on the most accurate accelerometer cut-points as well as by unknown effects caused by accelerometer position (wrist vs. hip) and output (single axis vs. multiple axes). The present study systematically evaluates classification accuracy...

OBJECTIVES To explore growth data (height-for-age, weight-for-age and BMI-for-age) of children living in poor socioeconomic conditions in rural areas of Chin State, Burma/Myanmar; and to compare these data with the growth and development z-score (GDZ) values for school-aged children and adolescents, provided by the WHO. SETTING A support and educational programme, run by the Swedish associati...

The prevalence of net list synthesis took raises great concern on routability of cell placement created with state-of-the-art placement techniques. In this paper, an accurate and efiienr placement routability modeling technique is proposed and incorporated into the prevailing simulated annealing approach. This accurate and eficient modeling is based on the supply versus demand analysis of routi...

results the mean distances between the crestal bone and the implant shoulder in group 1 were 1.01, 1.44, and 1.93 mm at the implant placement time, and at the 6 and 12-month postoperative intervals, respectively. in group 2, these distances were 1.35, 1.20, and 1.41 mm, respectively. there were no significant differences in the marginal bone resorption between the two groups (p > 0.05). conclus...
